Evaluation of the Poseidon Odin Scuba Regulator for Use In Cold Water
Authors: J. R. Clarke; M. Rainone; NAVY EXPERIMENTAL DIVING UNIT PANAMA CITY FL

Abstract: NEDU tested the breathing effort and susceptibility to freeze-up of the Poseidon Odin Jetstream SCUBA regulator. The regulator was tested in 28 deg F (-2 deg C) salt water, at depths to 198 fsw (60.7 msw) . Five samples of the model were tested. The probability of regulator failure was computed from the number of cold induced incidents, and the time to failure for each incident. Under these rigorous conditions, the probability of failure for the Poseidon Odin was very low (Pf = 0.074). There were also no high breathing pressure incidents during the resistive effort measurements with a 1500 psi supply pressure, even at RMVs up to 90 L/min. The Poseidon Odin is recommended for use in sea water at 28 deg F and depths to 190 fsw.
